- **✅ Enhanced HTML Reports**: Control names, working search, improved remediation display
- **✅ Enterprise Ready**: Production-tested with enterprise-grade architecture
- **✅ Performance Optimized**: Handles large-scale assessments efficiently
- **✅ Multi-Format Reports**: JSON, HTML, and CSV with detailed remediation guidance
- **✅ No AWS Config Required**: Direct AWS API calls based on Config rule specifications
- **✅ AWS Backup Controls**: 6 comprehensive backup infrastructure controls (3 IG1 + 3 IG2)
- **✅ Audit Logging Controls**: 7 comprehensive audit log management controls (CIS Control 8)
- **✅ Access & Configuration Controls**: 14 comprehensive identity, access, and secure configuration controls (CIS Controls 4, 5, 6)
